UNITED STATESA PATENT OFFICE.

GARRET G. JONES, OF RUSHSYLVANIA, OHIO.

IMPROVEMENTv IN LOC-OMOTIVE STEAM-ENGINES.

LSpecification forming part of Letters Patent No. 92, |93, dated July 6, 186i).

'llo all whom it may concern:

Be it known that I, G. G. JONES, oflush- Sylvania, in the county of Loganand State of Ohio, have invented a new'and valuable Improvement in Attachments to Driving-Wheels and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, referencel being hadv to the annexed drawings, making a part ot' this specification, and to the letters and figures ot' reference marked thereon.

Figure l of the drawings is a side plan view of my invention'. Fig. 2 is a bottom plan view" of the same. Figs. 3 and 4 are details.

My invention has relation to railroad-locomotives; and it consists, mainly, in the con struction and arrangement ot' novel devices by which thelweight of the front' end of the tender may be easily and readily thrown upon the drivingwheels of the locomotive, theobiect being to prevent such drivingwheels from sliding or slipping upon the track-rail.

In the drawings, the letter A represents a locomotive, and the letterB the tender thereof.

The letters C represent two bars-,hooked or pivoted over a transverse bar, D, which is arranged tothe bottom of the tender in the manner shown. The forward ends lof' bars C are round and pointed, and adapted to pass into and rest in and be removable from the eyes a, hereinafter mentioned. The letters c are slotted guides for the bars C. When the tender is disconnected from the locomotive the bars C rest upon the axles of' said tender.

The letter H represents a shaft lresting and rotating in suitable bearings in the frame ofV the locomotive in front of the platform, and letter 'i is a pinion aftixed thereto.

The letter n represents a lever attached to the shaft H, to which is affixed the dog o, working in the teeth of the pinion t', as shown.

The letter s represents a pawl so arranged that it may be actuated by the operators foot, and which works in the teeth of pinion t'. v

-The letter u represents an arm extending forward from the center of shaft H, to the front end of which is hingedv the slotted connectingarm o. This bar o is connected by pivot at its front end with the single bar y, the two forming together a species of chain, as shown in Fig. 3. i

The letter G represen ts a transverse pendent bar, suspended to the shaft C by the chain above mentioned, and the letters h are pendent arms attached to and swinging upon the respcctive ends thereof in the manner shown.

vThe eyes a, in which the front ends of the bars C rest when the tender is coupled to the locomotive, are formed in these pendent arms h.

The bearin gs of the axles ot' the front wheels of the locomotives are slotted, as shown on Fig. 4, the object thereof being to allow the wheels to remain on the track while the front end of the tender is raised. ,To operate my'device I raise the lever n repeatedly until the bar H raises the barsC and with them the front end -ot' the tender. To lower the bars C and relieve the driving-wheels from the weight ofthe tender, l place a foot upon the treadle of the pawl s. This movement releases the pawl from the teeth of pinion t, and the weight of the tender is restored to its appropriate wheels.

lhat I claim as my invention, and desire to secure by Letters Patent, is 4 1. The bars C, D, and G, connected 'by' a chain, as described, with shaft H, arranged substantially as specified.

.2 In combination-with the lifting devices herein described and shown, the slot-ted bearings (Fig. 4) for the' front wheels ofthe tender,

substantially as specified.

3. In combination with the shaft H, pinion i, bars C, D, and G,' the lever a, dog o, and pawl s, when constructed and arranged substantially as described.

In testimony that I claim the above l have hereunto subscribed my name in the presence of two witnesses.
